My beloved wife, Yukine, decided to re-enroll in university to obtain a qualification. Because she is sexy and popular, I can't stop feeling anxious. In a photo from a seminar drinking party, she looks so happy sharing drinks with some younger handsome guy. But knowing Yukine, she's probably bored of playing around, so I thought it was just a casual acquaintance. However, day by day, her return time became later and her messages became slower. Could it be with that flashy guy? Seduced at a drinking party, French kissing while drunk, skipping lectures to spend her days in raw creampie sex, and returning home with a soiled body... Just imagining it makes me shudder with rage. Surely, there's no way such a thing is actually happening.
